David Nail has plenty to be happy about these days, but that hasn't always been the case. During his recent No. 1 celebration of his smash hit "Whatever She's Got" in Nashville, the singer details his life-long struggle with depression and the turning point to finally seek help.

"I remember walking away and being so blessed to have been at this party, and all these nice things being said," Nail recalls of a pre-ACM Awards event with Chris Young a few years back. "I just should have been on top of the world, but for whatever reason, I couldn't physically get there. Or mentally get there either."

It wasn't until after his single "Let It Rain" rose to the summit of the singles chart that Nail realized things needed to change before they got any worse. "I've been going to counseling for a couple years now and take a lot of really expensive medicines and made a lot of changes in my personal life," he explains. "I've learned to not take life so serious and to kind of enjoy it. I've had a lot of help in doing that."

With a new, re-energized perspective, he set about recreating his upcoming album "I'm A Fire," out March 4. His new single is "Kiss You Tonight," hitting radio soon.
